Patented July 3, 1945 e OPERATED THEREBY in i Re nwick J. Sharp, Guatemala, Guatemala Application November is, 1943, Serial No. 510,821 16 Claims. (o1; 170 -75 This invention relates to. a pump remotely'operated by a windmill.

In many localities where the terrain is broken and abrupt, especially along streams or where seepages occur at thegfoot of hills or adjacent to elevated plots of ground, many systems, some of them windmill operated, have been devised for liftingthe water out ofthe low places and many instanceshaveproved to be of an impractical; unsatisfactory character... This has been due to a number of different causes, 'among them being the necessity for drilling very deep wells where it was deemed necessary to locate a wind mill upon a hilltop and also .to position the ,well directly thereunder: alsowells sodrilled often fail to afford access to the abundant supply of water desired which supply would have been readily available had connection been made with the streams, pools, or seepage often encountered 9 adjacent ;to the foot of thehill uponwhich it was desired to locate the windmill, but horizontally remote from a line perpendicular to the desired windmill site. e V

Another defect of pumping systems for localities like those above mentioned has been due to the provision of windmills located in low wind sheltered positions, so as to be nearer to the water to be pumped,but necessarily provided with large, expensive windwheels to offset the lack of wind available in such situations.

storingitat higher levels. These systems in ventionfwill hereinafter appear,

It is among themore important objects of the invention to overcome the aforementioned .dis-

advantages and others by providing meansfor elevating water from a lowland to a highland by placing the operating unit at a remotely situatedhigher level as well as at a considerable 3 horizontalj-distance from the pumping. unit, thereby minimizing the size of the operating unit,

the depth of well drilling and the size and weight of pumping units required.

Amongother important objects are: To p rovide as a connecting medium between the operating and pumping units an improved power trans; mitting connection; to improve upon the guide,

supporting and operating means utilized in contion; to gain additional wind power through selective sites of elevated terrain, andto lessen and" make easier the task of making repairs and replacements and reducing the cost of such instaljunction with said powertransmitting conneclations which for the reasons advocated have heretofore made such prohibitive.

H 1 Fig. 2 is a vertical section of thepower transmission wheel; the plane of sectionibe'ingindicated by angular line 22 .on' Fig. 3 theicableattacl iing device being shown in a"spaced"relation to the part of the wheel to which it is attachable.

Fig. 4is aperspective view of the meansffor stabilizing against buckling sion rod of the windmill. Referring in detail to th drawing, upon the upper part of the tower 5 is turnably mounted a gear casing Bone end of which carriesflae conventional wind wheel 1 fixed to the shaft 8, the opposite end of said casing carrying the conventional tail 9 whereby ,the wind wheel is di:

rected toward the wind.

The reduction gearing withintheycasing fidis operatively connected with the upper end of a vertical power transmission rod l l, the lower end of said rod being eccentrically pivoted tota large power transmission wheel l2 having a spindle or shaft portion. l3 whereby it us turnably supported upon the lower part of the tower 5' to be oscil lated in a vertical plane by said rod ll.

A pump I4 is shown remotely positionedin relation to the tower 5both as to downward and as to horizontal distance, said pumpbe'ing X operatively connected with the aforesaid power transmission wheel l2 by means of an inclined cable IS, the upper end portion of saidcable be ing attached to an upper. side portion of said wheel I2 and the opposite end portion being led over the pump pulley l6 and farther on having a whi h is arranged for vertical reciprocation. 1

The pump structure includes a cement basejill from which upstands a frame 2| uponithe upper parts of which is mounted the aforesaid pulley the power transmis Said weight is shown carrying a horizontal guide pin 23 with which cooperates a vertical slot 24 formed in a vertical guideplate 25 carried by the pump frame 2'l..- The upper part of the cable I is shownhaving a downwardly directed terminal run 26 to which is secured a weight 21 which.

counterbalances the weight of the cable I5 and the weight 22. i The pump I4 may either be located abovea well or adjacent to a pool of water, such well or pool being at the foot of the hill 29 upon which the tower 5 is built. A tank so .is shown statower. From the pump I4 up the side of said hilt to'rsaid tank leads a conduit 31 whereby said tank is supplied. from said well or'pool; i Referring to various mechanical detaiIs the cable. t5, if properly supported will operate: efliciiently even. if several hundred feet in-length, s

hence is "shown passingbetween and supported bva plurality ofpairs of antifrictionguide pulleys carried by posts 33." I a Also, the power transmission rod lief the windmill is shown stabilized by being linked to a rockable rod 35-w hiche iscarriedby thetower members 5a. Said rod carries a laterally extendingstaple-like link 36 which interlinks with a shorter Ll shapedelink 3'! carried by the rod H.

arrangement protects the long ,rod "II against buckling and yet allows it to shift laterally to ome. extent, as'it imparting oscillatorymovement tothe wheel l2 with which i-IQ-fi-S ecce'ntricallyconnected. ,Said ro d II is preferably madetubular in order to obtain maximum strength with minimum weight.

portions through which pass clamp screws. of. the capscrew type which screw into threaded sockets 43. provided for them in the; side portions of, the. power. transmission wheel I2, Said wheel 'i s preferably. of the light hol-lowtypeas-best shown in Fig. 2 where: itis seen to havev aplate 'likeside portion castintegralwith its spindlev I8 and to have a thick, substantial rim. portion M along the midwidth of. which extendsthe cable-receiving. groove 45.. The cable I5 occupies theinner portion of this. groove and. thedownbentpart. 4| .of the. clamping. bar 4.1!v occupies the outer. part of. said groove and is clamped down i against the cableunder a, sufii'cient. pressure to insure that-the. latter will not slipduring the. op-

. It is. desirable to provide for. operatively connectingfthelower end of the power transmission rod. with the power transmission wheelat' dif-' ferent distances. from its center, the connection being". made more eccentric for light winds and closer to the center whenthe windmillisflbeing o peljatedby a strongwind. With this end. in

view the wheel I2 is provided with a series'of seat formed by pivot holes 41 (three in the present embodiment) which are. differently spaced from the center of said wheel, and in Figs. 2 and 3 the connection between the rod. II and wheel I2 includes a pivotstud 48 extending through the outermost of the three holes shown, onto which screws a securing nut 49.

The operation of the apparatus will be readily understood from the foregoing description. However, an appreciation of the merits of the invention requires that it be observed-that the stationed by a pool. of water, or by a well much tioned on the top of this hill adjacent. to said...

, veration ofthe pump. The power transmission WheelaifordS an efiicientlmeansfor operatively windmill can be stationed. upon a hill of considerable height, where the. wind is much stronger 15.

and more constant than at lower levels, and yet the cable I5 can be extended over sloping terrain several hundred feet in length down to a pump lessin depth than would berequired if the well were drilled at the elevated point where the windmillis-stationed. I

The apparatus is of a simple, sturdy, durable character, 7: and is. particularly" serviceable fin tropical and semi-aridcountries, andhilly regions.
